我的 PHP 应用程序死于 fastcgi：意外的文件结束

Question

我在我的本地主机上更新到 PHP 7，但从那时起，任何时候我想在我的 nette 应用程序中从一个页面重定向到另一个页面，我都会收到错误：500 - 内部服务器错误.

我在搜索堆栈溢出时发现了一个与我的问题非常相似的问题：How to solve "mod_fastcgi.c.2566 unexpected end-of-file (perhaps the fastcgi process died)" when calling .php that takes long time to execute?。但是，我不处理大文件，我的连接会立即中断。

更新 7.3.2016

我从 php fast cgi 切换到 php-fpm，有趣的是问题仍然存在，但并不常见。有时重定向跳转到 500，有时不会。并再次记录错误：

Answer 1

另外，先尝试删除 Nette 缓存。

Answer 2

我终于找到了解决办法。这可能是 Nette / Cassandra 相关的问题。

由于对象 Nette\Security\Identity 而出现错误，在我将用户数据分配给它之后：

public function authenticate(array $credentials) {

  // Retrieve username and password
  list($email, $passwd) = $credentials;

  // Select user with given email from database
  $usr = $this->daoManager->getDao("AppUser")->loadByEmail($email);
  if ($usr == null || count($usr) == 0) {
    $msg = 'The email is incorrect.';
    $arg = self::IDENTITY_NOT_FOUND;
    throw new Nette\Security\AuthenticationException($msg, $arg);
  }

  // TODO Check user password
  // TODO Check verification      

  // Create identity - THE PROBLEM WAS HERE
  return new Identity($email, $usr['role'], $usr);
}

这是由于 $usr 数组中 Cassandra\Timestamp 的值 'registered' 引起的。从那时起，几乎所有重定向都因上述错误而崩溃。

以下代码修复了问题：

return new Identity($email, $usr['role'], $this->fixUserArray($usr));

其中：

protected function fixUserArray(array $user) {
  $result = array();
  foreach ($user as $key => $val) {
    if ($key === "registered") {
      $result[$key] = $val->time();
    } else {
      $result[$key] = $val;
    }
  } 
  return $result;
}
